There is 21% oxygen in the atmosphere and 300 ppm (0.03%) carbon dioxide. This translated to 700 times more oxygen than carbon dioxide.

At the peak of the inspiratory phase the alveoli contain how much of oxygen and carbon dioxide?

More oxygen than carbon dioxide.


Does plants also change oxygen into carbon dioxide?

Yes, but at night. It make oxygen more than it does carbon dioxide though. ---- Plants, like animals, do have metabolisms by which energy is generated through the oxidation of sugar, which produces carbon dioxide. However, green plants consume much more carbon dioxide, in the process of photosynthesis, than they produce by means of their metabolism, and they produce much more oxygen than they consume.


How much carbon dioxide is formed when 24.0g of carbon is reacted with 100.0g of oxygen?

24.0 g of carbon reacts with 64.0 g of oxygen to form 88 g of carbon dioxide.


Why carbon-dioxide supports the combustion of magnesium?

Carbon dioxide does not support the combustion of magnesium; it acts as a fire suppressant by displacing oxygen. Combustion requires oxygen, so the presence of carbon dioxide can inhibit the reaction by reducing the concentration of oxygen available for combustion.


How much carbon dioxide is made from oxygen and carbon during a fire?

If combustion is complete (which it usually is not) you will get a carbon dioxide molecule for every carbon atom or for every oxygen molecule depending on which runs out first.


What is the ratio of oxygen to carbon dioxide in the air?

The ratio of oxygen to carbon dioxide in the air is approximately 21:0.04. This means that oxygen makes up about 21% of the air we breathe, while carbon dioxide is present in much lower concentrations at around 0.04%.


Do plants give out carbon dioxide and take in oxygen or do plants give out oxygen and take in carbon dioxide?

Plants give out oxygen (from the breakdown of water) and take in carbon dioxide, which they use to form carbohydrates in the process of photosynthesis.However, at night and in darker conditions, plants still need energy, and use cellular respiration as animals do, taking in some oxygen and releasing carbon dioxide. This is normally much less chemical activity than photosynthesis, so green plants release much more oxygen than they use.


Do you breathe in carbin dioxide?

No, humans do not breathe in carbon dioxide. We inhale air that contains oxygen and exhale carbon dioxide as a waste product of respiration. Breathing in too much carbon dioxide can be harmful to our health.


Will the amount carbon dioxide the atmosphere soon be greater than the Amount of oxygen?

No, the amount of oxygen in the atmosphere is much greater than the amount of carbon dioxide. The current levels of carbon dioxide are approximately 0.04% of the atmosphere, while oxygen levels are around 21%.


What happens when the atmosphere has a higher percentage of carbon dioxide and lower oxygen?

The Earth will become hotter as carbon dioxide traps heat to keep the Earth warm. But too much carbon dioxide will cause the Earth to be more warm and that lead to global warming.


What would happen if you breathed in too much carbon dioxide?

Air contains oxygen, carbon dioxide, nitrogen, and other compounds. We take carbon dioxide into our lungs all the time, but our lungs keep the oxygen. However, if you were in a room with ONLY carbon dioxide, you would die--not from carbon dioxide per se, but from lack of oxygen.


Do any plants produce as much carbon dioxide as humans?

No, it's the other way around. Plants intake Carbon dioxide and put out Oxygen. In the theory of how the world formed, this is how the atmosphere got to contain Oxygen, from plants spreading over the continents and producing Oxygen.
